IConverter is a simple wrapper around cxxtools::iconvstream.
Often the result of a character-conversion is needed as a std::string.
This can be achived to let iconvstream to a ostringstream and get
the string from the ostringstream. IConverter simplify this.
example: convert a UTF8-encoded string to ISO8859-1:
\code
cxxtools::IConverter conv("ISO8859-1", "UTF8");
std::string utf8string = getUtf8String();
std::string iso8895_1 = conv.convert(utf8string);
// or functor-style:
std::string iso8895_1 = conv(utf8string);
\endcode
